I have size 15, low-volume, very flat feet. The most comfortable shoes I have run in are the Brooks Addiction, although I suspect this is due not to the motion control, but the shape....or my feet have a natural varus (or valgus?) angle to them and that motion control helps with that. I tried some Xero shoes, but not the Prios; the TerraFlex. The issue I have with most shoes, those included, was that when just standing around or walking around my house, I feel the need to rotate my heel to the outside to relieve some pressure/odd feelings on the area just forward of my heel; basically as if the shoe and my foot don’t line up exactly. Maybe it is an arch thing? I have switched to Altra Escalantes for runs, but the soreness I get AFTER the run is making me think they are maybe best served for shorter runs/speed work. That and, after a few months, my ankles still become sore as well. Thoughts? Which Xeros might work for me? Another brand? I want to switch to barefoot or minimalist shoes for running/everyday, but I don’t want to be uncomfortable as that rotating thing is annoying. Thanks!
